Quickly Paint Molding: One Coat, Done Right

how to paint molding with one coat of paint

Painting molding is a great way to enhance the decor of your room and make the colours on your walls stand out. It is a simple and budget-friendly way to improve the aesthetic of your home. The number of coats of paint you will need depends on the condition of the molding. If you have made extensive repairs, you will need to apply a coat of primer before the finishing paint. If you are painting over existing paint, you can skip the primer unless the trim was painted in a dark colour. To paint molding with one coat, you will need to prepare the surface by cleaning it with a damp sponge and allowing it to dry thoroughly. Then, apply painter's tape to the walls and ceilings surrounding the molding to protect them from paint. Next, apply your chosen paint, using a high-quality brush or roller. Finally, carefully pull the tape off the wall before the paint dries.

Choose the right paintbrush for the job

Choosing the right paintbrush for painting molding is essential to achieving a professional-looking finish. The type of paintbrush you should use depends on several factors, including the type of paint, the size and texture of the surface, and the level of detail required.

Firstly, consider the type of paint you will be using. Synthetic brushes are generally recommended for water-based paints, such as latex, acrylic, and water-based wood finishes. Synthetic brushes are available in various materials, including nylon, polyester, or a blend of the two. These synthetic bristles offer exceptional paint capacity and faster results. Nylon brushes, in particular, provide a smooth finish and excellent paint pickup, while polyester adds stiffness and control. Natural bristle brushes, on the other hand, are more suitable for oil-based paints, varnishes, and enamels. They provide a super-smooth finish, especially when used on smooth surfaces.

The size of the paintbrush is another important consideration. For painting molding, it is generally recommended to use a smaller brush that allows for greater control. A 1" to 2 1/2" angled sash brush is ideal for projects that require precision, such as painting intricate details on molding or trim work. The width of the brush should be slightly narrower than the width of the molding or trim you are painting.

The texture of the surface you are painting will also influence your choice of paintbrush. If you are working with a smooth or slightly textured surface, opt for a softer brush with flexible bristles. Soft brushes leave fewer brush marks and are ideal for achieving an ultra-smooth finish. For rough or textured surfaces, choose a stiffer brush with more durable bristles. Stiff brushes are better suited for holding thicker coatings and creating crisp lines when cutting in or painting around molding or trim.

Additionally, consider the handle length of the paintbrush. Short-handled brushes are ideal for painting in tight spaces, such as corners or intricate molding details, as they provide better control and manoeuvrability. On the other hand, long-handled brushes are more suitable for covering large, open areas as they can hold more paint and cover a wider surface area with each stroke.

Lastly, don't underestimate the importance of quality. A high-quality paintbrush will make your job easier and yield better results. Look for brushes with flagged bristles, which have split ends that hold more paint and provide a smoother finish. The bristles should be flexible, springing back into shape when pressure is released, and they should not shed easily. A comfortable handle made from unfinished wood can also enhance your painting experience and reduce hand fatigue.

Prepare the surface by cleaning and sanding

Preparing the surface of your molding is key to achieving a professional-looking finish. Start by cleaning the surface with a damp sponge or cloth to remove any dirt, dust, or grime. If you're dealing with tough stains, use an abrasive cleaning pad, but be sure to rinse the surface well afterward. You can also use a soft-bristled brush to clean crevices gently.

Once the surface is clean, it's time to sand it. Sanding will help create a smooth base for your paint to adhere to and ensure a uniform finish. Use fine- or medium-grit sandpaper or a sanding sponge, and always sand with the grain of the wood to avoid leaving blemishes. If your molding has a high-gloss finish, sanding will help prepare the surface to accept the new paint or primer. After sanding, use a damp cloth or vacuum to remove any dust. If your molding has nooks and crannies, use a vacuum with a nozzle that has a brush-end to reduce the vacuum power and prevent sucking the spackling out of any holes. Finally, give the molding a thorough wipe-down with a clean, damp rag to ensure no dust or debris remains.

Prime the moulding

Priming is a crucial step in painting moulding and will ensure your work has an even finish, brings out the colour of your paint, and prevents cracks and fading. If your moulding is pre-primed, you can skip this step, as most mouldings sold at retail stores come with factory-applied primer. It is only necessary to prime solid pine or unprimed finger-joint moulding.

First, wipe down the moulding with a clean, slightly damp rag or sponge. This will remove any dirt and grime from the trim. If the trim is new or already smooth, lightly sand it using 120-grit sandpaper until all shine disappears from the trim. If the existing trim has a high-gloss finish, sand the surface before painting to help it accept the new primer or paint.

Next, fill in any holes, dents, and cracks with a lightweight spackling compound. When the spackle dries completely, lightly sand the spackled areas using 120-grit sandpaper to smooth out the surface. Use a tack cloth to remove any sanding dust from the trim. Vacuum the moulding to prevent dust and debris from sticking to your primer.

Now you are ready to prime the moulding. Use a wood primer, applying it using a high-quality paintbrush of a thickness that suits the wood you are painting. Depending on the product, you may not need to apply a separate undercoat. We recommend starting the project with an acrylic primer, which delivers maximum hide and a uniform finish. Let it dry thoroughly before applying the next coat. Typically, you will need to apply 1-2 coats. Make sure you wait for the first coat to dry completely before adding a second coat.

Apply the paint

Painting molding can be a tedious process, but the results are worth it. Here is a detailed guide on applying the paint:

Prepare the Paint and Brushes:

Before you begin, thoroughly mix the paint with a paint stick and pour it into a clean paint tray. Use a high-quality brush that is suitable for the type of paint you are using. For water-based paint, choose a nylon/polyester brush, and for oil-based paint, opt for natural bristles. An angled brush, such as a 1½- or 2½-inch angle sash brush, is ideal for painting molding.

Dip and Tap:

Dip your brush into the paint, covering no more than half an inch to one inch of the brush. Remove excess paint by tapping the brush gently on the side of the paint can or tray. Avoid wiping the brush, as this can push the paint towards the centre, leading to drips.

Paint with Smooth Strokes:

Work in Sections:

Depending on the width of the molding, you may need to use multiple long, parallel brush strokes. Wider trim may require three or four strokes, while thinner trim may only need one or two. Work in sections, ensuring that each stroke starts in an unpainted area and works towards the painted sections.

Remove Tape Promptly:

Before the paint dries, carefully remove the painter's tape from the walls and molding. Removing the tape immediately is crucial to prevent the tape from damaging the walls or the molding itself.

Remember to take your time, follow the instructions on your paint can, and allow adequate drying time between coats. With careful preparation and a steady hand, you can achieve a beautiful, professional finish on your molding.

Install the moulding and caulk the seams

Painting moulding can be a quick and easy way to make a room stand out. Here is a guide on how to install the moulding and caulk the seams.

Install the moulding

Before installing the moulding, you should prepare the moulding by priming and painting it. Start by wiping down the moulding with a clean, slightly damp rag. Then, sand the moulding with a medium/fine grit sanding sponge or paper. We recommend using 220-grit sandpaper. Next, vacuum the moulding to prevent dust and debris from sticking to your primer. Finally, prime the moulding with a primer of your choice. You will typically need to apply 1-2 coats of primer, waiting for the first coat to dry completely before adding a second coat. Once the primer is dry, you can apply your top coats of paint, typically two coats, again waiting for the first coat to dry before applying the second.

Now that your moulding is prepared, you can install it. If you have not already, fill any nail holes and repair scratches, dents or damaged surfaces. You can do this by using a non-shrinking filler such as caulking. Once the filler is dry, install your moulding using nails.

Caulk the seams

Caulking the seams will give your moulding a finished look and will cover up any leftover gaps. When applying the caulk, try to use consistent pressure. We recommend cutting your caulking tube tip at a 30-degree angle, as this will allow for better application. To apply the caulk, start at one end of the trim and, at a 45-degree angle, place the nozzle of the caulk where the trim meets the wall or the gap. Pulling the trigger of the caulk gun slowly, use enough pressure to get the caulk out of the tube and start to fill in the gap. Simultaneously, squeeze the trigger and move the nozzle along the gap, filling it in with a bead of caulk and ensuring it is even.

You can smooth the caulk with your finger, but make sure to keep your finger clean and damp to avoid leaving ridges. Alternatively, you can use a damp cloth to wipe away any excess caulk.
